Abstract :
This paper describes a distributed system of cameras for tracking feature points in 3-space. A low-cost camera unit has been designed using off-the-shelf components that include a small CCD board camera and two servo-controlled mechanisms for pan and tilt. Triangulation is used with two or more calibrated cameras in a network of cameras to compute the location of a point in 3-space based on camera positions and pan/tilt angles. Experimental results demonstrate the advantage of using the redundant data from multiple pan/tilt cameras
